Step 1: Privatize and sell it for peanuts to fellow billionaires

There’s no way national rail can be a profitable service, and certainly not without huge investments in infrastructure. It’s only the northeast corridor that’s profitable, but quite a few other places can be but only after huge infrastructure investments. Those investments are coming from a wholly private company.
Technically Amtrak already is a private company, but owned by the Department of Transportation. Those owners need to pony up for rail infrastructure the same way they’ve always ponies up for highways infrastructure.
